Connecting structure and a display device with said connecting structure

Abstract

Providing a connecting structure for connecting first electrodes formed on the upper surface of a first substrate to second electrodes formed on the upper surface of a second substrate glued on the upper surface of the first substrate by an electrically conductive member, wherein the second substrate is smaller in its outer size than the first substrate, the first electrodes are arranged on the first substrate around the periphery of the second substrate, a gap is formed between the first and second substrates at the peripheral edge of the second substrate, an insulating resin is arranged near the first electrodes so as to cover portions of the side surfaces of the second substrate and to fill the gap between the first and second substrates, and the electrically conductive member is arranged over regions leading from the first electrodes through the insulating resin to the second electrodes.

The invention claimed is: 
     
       1. A connecting structure for connecting first electrodes formed on the upper surface of a first substrate to second electrodes formed on the upper surface of a second substrate glued on the upper surface of said first substrate by an electrically conductive member,
 wherein said second substrate is smaller in its outer size than said first substrate, said first electrodes are arranged on said first substrate around the periphery of the second substrate, a gap is formed between said first substrate and said second substrate at the peripheral edge of said second substrate, an insulating resin is arranged near said first electrodes so as to cover portions of the side surfaces of said second substrate and to fill the gap between said first substrate and said second substrate, said electrically conductive member is arranged over regions leading from said first electrodes through the upper surface of the insulating resin to said second electrodes, and the plane of said second substrate, which plane is opposed to said first substrate, is provided with a third electrode at least at the end periphery of said second substrate, and 
 wherein the portions of said third electrodes near said first electrodes are removed.
